Nano Crystal Emerald

Nano crystal Emeraldis a name for a group of new materials for jewelry.

The crystals grown in amorphous substance by high-temperature synthesis at 1500-1750°C.

The chemical composition of these materials is a mixture of oxides including silica, zirconia, alumina, zinc, lithium and magnesium oxides. Nano sized crystals are homogeneously distributed in amorphous matrix.

As a result materials with various physical-chemical properties based on spinel, gahnite, sapphirine and other crystals are formed.

Hardness of the suggested materials is 6.5-7 by Mohs scale,

Refractive index is 1.5-1.7,

Density is2.7-3.2 g/cm3.
